Thisinvention relates to a sterilizer for towels and the like, the general object of. the invention being to provide a tank containing sterilizing liquid and a drum 'rotatably arranged in the tank and extending down into the liquid with cables for causing the artlcles to be sterilizedto move around with the drum so thatthey will be immersed in the liquid and then carried upwardly "with the drum under a spring-pressed rollerywhichremoves superfluous liquids from the 1 articles and finally the articles are discharged adjacent the points at which theyar'e introduced into the apparatus.

Y ln-theseldrawings, theinumeral 1 indicates a tanker housing which is preferably ofr'eca plicat o filed october 1, 1931. serial- N y Thisinvention also consists in certainother tang ar shape with its hinged top 1. of semicircular shape and said tank or housing has in its? front an: elongated opening 2 .for the introduction of the articles -tobe sterilized,

' and-an elongatedslot 3 for the discharge of C said articles. 1 a F r i; o

A hinged shelf .4 is located below thefslot 2;: and is supported inoperative position by the pivoted leg 4"". Upper and lower down wardly slopingplates 5'are; located an the interior face of the front wall of the housing above and below the sl-ot 2, and upwardly extending plates 6 extend from theu'pp'er and lower edges of the.slot 3. v A frame 7 is located 'n the-tank or housing and'is composed of'the two side. plates; 7*,- 0'f the shape shown, connected together by the upper cross bar 28, the rearcross bari28 and the two front cross bars 18. TA shaft {iris journaled in said frame and supportsa drum am 10. O'ne endof the drum carries a-rin'ggear 11 with which meshesapinion12 onitheFshaft 1 13 of a motor supported fromthe frame and located in a small'casing lfiat oneen'd-of the housing, and the circuit of-Whi'ch is controlled by suitable switches. Thuswhen thecircuit of the motor is closed, the motor will Jrotate thedrum. Four pulleys 19 are carried by the bars 18 and-four pulleys 20 are carried bythebracle ets '17 connected tothe ends of the b.ars 1"8.

The pulleys are arranged as shown in Fig.3.

a A pair of cables 21 pass around. the drum and these cablespass'overthe guide pulleys e 19 and 20 aslshown in Fig. 3 so that the cables as they pass over the pulleys are caused to .travel :away from each other,- thus leaving a wide space between the cables at the front of the drum so that articles introduced through i390 the slot 2 and dischargedfrom'the slot 3; can

1 pass to'and from the'drum withoutinterfen ence on the part of the cables. I As the-cables contact the drum over the greater part ofthe circumference thereof, said cables will travel with-the drum; I I-; 3

Curved arms 22 arepivoted to the frame, one adjacent each end of 'the housing as showngat 23iand a rjOllerQ4, hasjits pintles j'ournaled in'the free ends .of these arms. at

This-roller is formed with a pair of annular I grooves through which cables 21 pass and a spring member 26 has its ends engaging the arms 22 for pressing the roller 24 yield- I ingly against the drum. The tension of this spring is adjusted by means of a set screw 27 which passes through the top bar 28 of i the frame 27. a

endthereof, and a' thermostat device'30 is associated with this element for automatie cally controlling the heating ofthe liquid in the housing. A sight gauge 31is in communication with the lower part of the housing to show the liquid level therein. Ather- .mometer may beassociated with this sight gauge to indicate the temperature of the li-quid 1 within the same.

the bottom of the housing, and coils '34 of tubing are connected to .thissmall tank as shown at '34,the other end of the tubing being connected to an outlet pipe 35 which contains avalve- 36, thispipe leading to a sink or other point of use. These coils-34 are located in the housing 1 and rest upon the top of the small tank 33 so thatthe water passing from the tank 33 through these coils to the pointof use and the water passing through'these' coils is heated bythe hot water in the housing when the electric heat- .ing means 29 is in use. A supply pipe 37 con .taining a valve 38 is connected in thetank ;33. Thelower fitting 39 'of the gauge is formed with an extension which is incom- 'munication with tank 33 by a connection 37 anduwith the bottom of housing '1 by a connection 35 and said fitting 39 has adrain valve 40 at its bottom for drainingboth tanks and valve 41 in the fitting when open will cles to a'position where they will be received, between the cables: and the drum and thus caused to move with'the drum. Thus the articles will belcarried through the sterilizing liquid and then will pass upwardly with the drum under the pressure roller 24 where superfluous liquid will beremoved and final- "lythe articles willengage the lower. plate 6 which will remove the articles from the drum and direct themthrough the slot 3 and to the shelf 4. V

I The coil of tubing'in the small tank will provide a supply of hot water, when the A small'tank or chamber 33 is located electric heating element 29 is in use, for a sink or the like, though it will be understood that the device can be used with the sterilizing liquid hot or cold. 1

When desired, a sterilizing preparation can be introduced into the water in the housing by lifting the hingedtop; r It. is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent. I

It is .to be'unde'rstood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within thescope of the appended claims. Having thus described:ourinvention, what we claimas new is 3* s; f
